Potato leafroll virus molecular interactions with plants and aphids: Gaining a new tactical advantage on an old foe

Abstract

Potato leafroll virus is a member of the genus Polerovirus in the family Solemoviridae. Potato leafroll virus (PLRV) is exclusively transmitted by aphids in nature. The coat protein and readthrough protein constitute the structural components that form the icosahedral capsids of assembled virions. Recent advances have revealed the structure of the virion as well as molecular interactions among the virus, host, and vector. While planting certified virus-free seed is the best way to ensure a healthy crop, extensive molecular tools are now available to develop alternative approaches for PLRV management.
